摘　　要：The aim of this work is to study the effects of the electret property of natural biopolymers (such as collagen) on tissue repair. Type I collagen was prepared from pigskin,and polarized by using the TSDC (thermally stimulated depolarization current) technique. The polarized materials are used for cell culture. and then the cell growth curve is drawn. It was found that the polarized biomaterials accelerated cell differentiation. which indicates that they may be applied in the biomedical field.研究天然生物高分子（如胶原）对组织损伤修复的影响．从猪皮中提取的I型胶原通过TSDC技术极化，并测试其驻极化前后的TSDC变化．将极化的材料用于细胞培养．得到了细胞生长曲线．实验证实，极化后的材料能加速细胞的生长．有可能用作生物医用材料．
